The Barologger Series 5 is set above high-water level in one location on site. One Barologger can be used to compensate all Leveloggers in a 30 km (20 mile) radius and/or with every 300 m (1000 ft.) change in elevation. The Levelogger software data compensation wizard automatically produces compensated data files using the synchronised data files from the Barologger and Leveloggers on site. The Barologger 5 uses pressure algorithms based on air rather than water pressure, giving superior accuracy. It records atmospheric pressure in psi, kPa, or mbar.
